Yes. Slide 12 of http://k9yc.com/7QP.pdf shows two Jackite poles mounted
to a plate at the top of the pneumatic mast on W6GJB's contesting
trailer, supporting wires that form a 40M dipole. The next slide shows
how we use surplus modular military surplus mast sections to for a
tower. The legs are two 4-ft sections, which gets the tripod high enough
that mast sections can be added and pushed up to extend it. It's no
trick to get it up 25-30 ft
Later slides show an 80M inverted V rigged about 3 ft below the 40M dipole.
W6GJB found a vendor selling the tripod fittings at Dayton some years
ago. This concept is something that K7JA showed in a talk about Field
Day ideas, I think at Visalia.
